-v IMPROVEMENT In SPRING-Poweas.

Speciication forming part of Letters Patent No. 176,620, dated April 25, 1876; application filed February 9,1876. f

' tain new and useful Improvements in Spring- Powers, Snc.; and do hereby declare the'foL lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in which the figure is a front elevation of my invention.

The object of my invention is primarily to furnish a spring-motor of great power and effectiveness.

The nature of my improvements consists in .the peculiar construction, combination, and arrangements ofpartswhereby the expansive power of a spring will be exerted equally in both directions of its length.

Referring to the accompanying drawing, A and A' represent two springs sustained between levers U C. Said levers are each pivoted at c in fulcrum-blocks D D, said blocks being connected' by a rod, E, which passes through a spring, e. F F are U-shaped rods,

having their respective ends fastened in plates ff, which form end bearings or heads for the springs A A'. G is a plate which passes between the springs'A A', havingan extension, g, for lthe attachment of the motor to any convenient fixture. H H represent hooks which connect the ends of the levers C G with the rods F F.

I he springs AV A' will be compressed by any suitable mechanism, preferably by gearing I K, located between the opposite ends of the levers G G. The ordinary or any suitable arrangement of pawl-and -ratchet mechanism will, of course, be employed in connection with the gearing I K, so that the chain may be wound upon its drum without affecting the parts to which, through said gearing, the power of the motor is afterward transmitted. The compression by this means of said springs will cause the fulcrum-spring e to be also compressed, the rod E passing into the blocks D D as the latter approach one another.

heads f causes their expansive force to be exl ert`ed equally in both directions of their length, thus obtaining greater uniformity,

steadiness, and power than could be otherwise achieved..

The spring e is used as a means of reenforc, ing the springs A A', as when compressed it aids in distending the levers C C.

This arrangement of spring is also applicable to railroad-car draw-springs, and other springs where great resisting power is required. l

What I claim as my invention is- .1. Springs A A' placed between end plates f f, and connected by rods F, substantially as described, so that the expansive force of said springs will be exerted in both directions of their longitudinal axis, substantially as set forth. l

2. rlhe combination of the springs A A', rods F F, and intermediate plate-end or bearing G, substantially as shown and set forth.

3. In combination with pivoted levers C G, the spring e, affording elastic fulcra for said levers, substantially as shown and described.

4.111 combination with the springs A A', rods F F, and heads f, the levers O C, substantially as shown and described.

5. Thev combination of springs A A', levers C C, fulcra D D, spring e, rods F F, and plates or heads ff G, the several parts being arranged and combined for operation substantially as shown and described.

In testimony that I claim the lforegoing I have hereunto set my hand.
